Nascent Behaviors

Nascent Behaviors

Nascent behaviours are behaviours that look niche, trivial or fringe now and turn out to be mass-market once the friction around them drops. It is Nir Eyal's heuristic from Hooked, published in 2014, for where designers should look for habit-forming opportunities. It is an argument from historical cases rather than a tested claim, and the cases are selected with hindsight, so the pattern it shows is survivorship rather than a base rate.

What it is

The heuristic sits alongside two others in Eyal's account of where new habits come from. One is enabling technology, using the investor Mike Maples Jr's wave model of infrastructure, then enabling technology, then interface. The other is interface change. The claim connecting them is that wherever new technologies suddenly make a behaviour easier, new possibilities are born.

The nascent-behaviour version says something slightly different and more useful. The behaviour is often already there, practised by a small and apparently odd group, and what is missing is not desire but an interface cheap enough to make it ordinary.

Eyal's cases are the Brownie camera and early Facebook, both of which looked like toys for a small set of early adopters before the behaviour they enabled went mainstream. He pairs them with a running joke about expert dismissal of the technology that was about to make the behaviour easy, including a 1995 magazine piece by Clifford Stoll published online under a headline dismissing the internet, and a line attributed to Ferdinand Foch in 1911 about aeroplanes being interesting toys of no military value. The Stoll piece is real. A primary source for the Foch line was not found, and this publication treats it as attributed rather than verified.

In effect

The same phenomenon has been described from other directions, which is the best argument that it is real. Clay Shirky's mass amateurisation is an untapped behaviour, amateur publishing, that suddenly had an interface cheap enough to make it mass. Tim Wu's account of idle office attention describes a dormant and unmonetised behaviour that nobody with resources thought to chase until amateurs got there first.

For a designer or an investor the practical move is to look at what a small group already does with obvious friction, rather than at what a large group says it would like. Stated preference produces features. Observed inconvenience produces products.

The obvious objection is the one the heuristic does not answer. The lesson is not that experts are stupid. It is that a behaviour nobody takes seriously is sometimes waiting on the interface layer, and the word doing the work is sometimes.

What it does not say

It does not say that fringe behaviours usually become mainstream. The book counts the ones that did and not the ones that stayed fringe, so there is no base rate here at all.

It does not say the experts were foolish. Most dismissed technologies were correctly dismissed, which is exactly why the surviving quotations are funny.

It does not verify its own quotations. The Foch line circulates widely and should not be quoted as established.

And it is not a research finding. It is a sourcing heuristic for product designers, and replication does not apply to it.
